Does a Common Virus Aid the Spread of Cancer?

08-17-2011

The University of San
Francisco’s
Juliet Spencer, associate professor of biology, has been awarded a $412,000
National Institute of Health grant for cancer research – one of the largest
competitive federal grants garnered by an individual USF faculty member in
recent years.

Spencer’s latest research expands on earlier workthat examined a variant of the herpes virus (HCMV), determining how it is able
to lay dormant and go undetected in humans, sometimes for decades, before
attacking the immune system.

“Our project focuses on the connection to cancer, but in a
slightly different way than other studies,” Spencer said. “We don’t think the
virus needs to infect the cells to cause cancer. We think that infected cells
may produce a substance that causes healthy cells to be more likely to become
cancerous.”

If Spencer is able to demonstrate the connection between
HCMV and breast cancer tumors, it could lead to changes in the diagnosis and
treatment of cancer to include antiviral medicines in addition to chemotherapy
to the benefit of patients’ prognoses.

“There’s still a lot of work to do,” Spencer said.
“But the potential for human health benefits is tremendous.”
